AI总结:

本文针对可积$AdS_2$超弦无质量散射的形状因子展开研究,借助Fendley $S$矩阵的极限性质,构建满足假设的相对论修饰因子积分表示,证明交叉与幺正性关系,给出两粒子形状因子约束的解。

摘要:

本文首次开展可积$AdS_2$超弦无质量散射的形状因子研究,该体系中可利用$S$矩阵的差形式来实现相对论形状因子自举法。由于该$S$矩阵的非标准特性,传统方法不再适用。我们借助了如下事实:无质量$AdS_2$的$S$矩阵是Fendley发现的一类性质更优的$S$矩阵的极限。我们证明了此前猜想的无质量$AdS_2$修饰因子,与De Martino-Moriconi针对Fendley $S$矩阵提出的改进修饰因子的极限完全一致。在找到一种构建满足特定假设的相对论修饰因子积分表示的方法后,我们给出了交叉关系与幺正性关系的解析证明,并提出了两粒子情形下形状因子约束的一种解。

英文摘要:

In this paper we initiate the study of form factors for the massless scattering of integrable $AdS_2$ superstrings, where the difference-form of the $S$-matrix can be exploited to implement the relativistic form factor bootstrap. The non-standard nature of the $S$-matrix implies that traditional methods do not apply. We use the fact that the massless $AdS_2$ $S$-matrix is a limit of a better-behaved $S$-matrix found by Fendley. We show that the previously conjectured massless $AdS_2$ dressing factor coincides with the limit of the De Martino - Moriconi improved dressing factor for the Fendley $S$-matrix. After finding a method to construct integral representations of relativistic dressing factors satisfying specific assumptions, we obtain analytic proofs of crossing and unitarity relations and propose a solution to the form factors constraints in the two-particle case.
